:at 282 Western'Avenue, Blue `sland,i1fithe l `county of Cook andr State'of Illinois, "haye invented a new and vuseful Improvement in BurStands, of whichlthe is fa specification. y This invention relates torir'r'ipr ifvements in bur-stands; for example, "such `as "areused bydentists for holding thel burs 4or drills used in vtheir work. y

`Such burstandjs, as vheretofore made, are

rordinarily provided vjw'ithjholes oivcavities closedat the bottom, 'forholdinfgfjor'fsup-- porting the b urs. Such holes orcavities are veryobjectionable, owing/toy the fact that l' they form receptacles orfandretain iilings thisway they soon'become un'sanitary, and often interferewithvthe properv support 'oft the bur. Since such holes or4cavitiesla'ecomeiilled oiipartially,filledwith dirt, they alsopreventthe burs'ffriii'coming to the bottom thereof, Solthat it isdifficult to know the exact length of a bur by observing the projectingpart.kv i y f i In my improved bur-stand the objections' to stands asheretofore ordinarily'made, and as noted above, are done away with. -Mystand is so constructed that it can ybe easily and cheaply made. It isalso neat in appears ance, and supports the burs without any holes orcavities closed at the bottom, so that it can be easily cleaned and keptin a sanlytary condition. All of the bursin my improved standy arealways supported at the saine length so that the exact length of a burcan always be noted hy observing it in position in the bur-'stand Theabove referred to features and advantages of my bur-stand and otherswill ap` pear more fully as I proceed with my specication.A x

A form'of device embodying the features of my invention is shown in theaccompany- 'ing drawingszin which Fig. l is avertical sectional viewtaken as indicated hy the line 1 of Fig. 2 and F ig. 2 is a broken planviewl with the glass cover shown 1n section.

' As ,shown in the drawings, the bur-stand comprises a circular basepart ypressed orasuitably formed from sheet metal or other suitablematerial. This base' part includes a p circular disc 10 having an outerdown- [12'forming@#Shoulder'13.

The discs are 'equally spaced "'on the 1vsleeve '30 by seriesof washers 40 placed betweeny each adjacent two.kThe ends of the sleeve 30 are turned outwardly or riveted as indicatedby soy 4-1 in order to clamp the discs and washer together and hold themall tightly on the sleeve. It is obvious that by this construction allthe discs7 washers and sleeve can be vided with a row of' holes 51, andVsimilarly the discs 34 and 35 are provided with a rovv` of holes 52 and'the discs 35 and 36 with a row of holes 53. The holes 6 arranged ineach pair of discs are in vertical alignment so that lours placedtherein will be held vertically. It will he noted that under each :suchrow of holes is a portion of a disc which.

is vnot perforated to serve as a support torv `the bottom ends of theburs. For example. the disc 31 supports the hurs in the holes 5() such`as indicated by 75. i disc 32 inside of the holes 5() acts as a sup-Likewise the port for the burs 77 standing in the holes 51.

Likewise, disc 33 supports the bottoni ends of the hurs 78 in the holes52, andthe disc 34 supports the hurs 79 in theholes. A glass bell shapedcover 90 is provided as shownk adapted to rest on the flange 112.

It will'he clearly vseen vthat by this conilo f fications.

struction withy discs to support the burs,

`that the ends of none rest in any holes or cavities. By suchconstruction, filings from the bursV themselves 'or any other dust ordirt falls on-to theat discs from which it can be easily removed bymerelyblowing sideways through the bur-stand or *tilting broadly aspossible in view of the prior art.

What I claim as new and desire to secure by Letters Patent; i

. 1. A bur-stand comprising a base, a support projecting upwardlyfromsaid base, and a plurality of horizontally arranged spacedapartplates mounted on said Support and provided with holes adapted toreceive and support burs, whereby said stand maybe readily cleaned by ablast of air, or the stand and burs sterilized by dipping the stand withthe burs in place in a sterilizing solution. t l Y 2. A bur-standcomprising a circular base, a central post mounted on said base,a sleeverotatablymounted on said post, and a plurality of horizontally arrangedspaced-apart platescarried by said sleeve, said plates be- -ing providedwith holes adapted to receive and support burs, whereby said stand maybe readily cleaned'by a blast of air, or the stand and burs sterilizedby dipping the stand with the burs in place in a sterilizing solution. y

' 3. A bur-stand comprising a base, a support projecting upwardly fromsaid base,v a sleeve rotatably mounted' on said support and apluralityof horizontally arranged spaced-apart perforated plates carriedby said sleeves, the perforations in a plurality of said plates being inlvertical alinement and adapted -toreceive burs,and a platearrangedbelow said peri'orations -to present an imperforate surface tothe lower ends of burs lying within said perforations whereby to retainsaid burs in place.

Il. A burestand comprising a base, a support rising from said base, asleeve rotatably mounted on said support, a plurality of spaced-apartplates carried by saidy sleeve and having bur-receiving perforationssome of which aline vertically with the perforations inv anv adjacentplate and others of which are in staggered relation thereto.

In testimony whereof I have hereunto set fmyphand and sealthis 7th dayof September, 1921.
